-## compute the factorial of 5, and return the result in the exit code
-#
-# Uses syntax sugar for:
-#   rm32 operands
-#
-# To run:
-#   $ ./translate_subx init.linux [01]*.subx apps/factorial.subx -o apps/factorial
-#   $ ./bootstrap run apps/factorial
-# Expected result:
-#   $ echo $?
-#   120
-#
-# You can also run the automated test suite:
-#   $ ./bootstrap run apps/factorial test
-# Expected output:
-#   ........
-# Every '.' indicates a passing test. Failing tests get a 'F'.
-#
